Oracle 10 DBMS_MONITOR跟踪和分析其它session SQL

1. session 信息

查看当前session信息语句

select sid, serial#, username, machine
from v$session
where type != 'BACKGROUND'
and username = 'SYS'；

-- session 1 ----

session_id = 146
serial# = 18

-- session 2 --

session_id = 140
serial# = 31

2.执行过程

1）-- session 1 ----
-- start trace --
EXECUTE DBMS_MONITOR.SESSION_TRACE_ENABLE(session_id=>140, serial_num=>31, waits=>TRUE, binds=>TRUE);
#############################
2）-- session 2 --
执行SQL语句
###########################

3）-- session 1 ----

select sql_trace, sql_trace_waits, sql_trace_binds
from v$session
where sid = 140;

-- end trace --
EXECUTE DBMS_MONITOR.SESSION_TRACE_DISABLE(session_id=>140, serial_num=>31);

4）生成跟踪文件
跟踪结束自动生成session 2 SPID跟踪文件oradb1_ora_3732.trc

3.查看结果

1）查看session的SID、SERIAL#，process的PID、SPID

SQL> select s.sid, s.serial#, p.pid, p.spid
2 from v$session s, v$process p
3 where s.paddr = p.addr
4 and s.username = 'SYS';

SID SERIAL# PID SPID
---------- ---------- ---------- ------------
140 31 16 3732
146 18 17 4072

2）生成session 2 分析结果文件

tkprof C:\oracle\product\10.2.0\admin\oradb1\udump\oradb1_ora_3732.trc 3732.txt
